[jmsl] MidiInstrumentSending Program Message

[jmsl at music.columbia.edu]

Hi Chi

Yes, sendin the program change is part of opening the instrument.  I 
could change this behavior but then existing applications that expect 
this behavior will break.

Maybe the best thing to do is for JMSL midi to include a user-definable 
switch which only sends program change N once on a particular channel. 
This could run into scary side effects so it would have to be something 
the programmer took responsibility for and programmed for it.  Maybe 
something like the following (with less ridiculous names eventually):

JMSL.midi.onlySendMIDIProgramOnce(true);
JMSL.midi.clearMIDIProgramChannelTable();   // do this before each launch!
myPiece.launch(JMSL.now());

Have to think about this
